I saw this exact pair at a local running store, and although I believe in shopping local, Amazon was $30.00 less than the local store.I felt bad asking to try them on, so I took. chance and ordered a half size up, which as a runner I know to do. I was apprehensive but hopeful they would be a even better replacement for my old pair of Mizuno Wave's, and they were!In truth I purchased the Mizuno's with a $60.00 insert at the suggestion of the running tech at the local store. They never really fit well, and the insert hurt, but I kept them anyway. I even ran a few (painful) races in them, but I have a few 10K races and a half marathon in the fall, so I knew it was time to be rid of them.The Vazee are amazingly cushiony, have enough for the normal amount of foot swelling that occurs when running, and are light as a feather. No insert needed!I plan to get another pair as I've mucked them up in a trail run.Highly recommended!!!
